In the accompanying drawing the numeral 9 denotes the head of my improved scalp treating implement which may be of any desired shape and composed of any suitable materiaLjpreferably some composition of matter. 'As herein shown this is of rectangular shape when viewed in plan. A chamber I is formed in the head, as shown in Fig, 4 of the drawing, and an opening II extends rearwardly from said chamber, opening out at the rear side of the implement. A tube 8 terminating in an enlarged end or collar I2 is secured withiny the opening Il and projects from the back edge of the head 9, this collar having a bayonet slot I3 for the reception of a pin projecting from the side of a sleeve I4 having a knurled enlargement I by means ofi which the sleeve may be turned to engage said pin in the bayonet slot or disengage it therefrom.

The outer end of the sleeve comprises avnipple I6 to which a flexible tube I1 maybe secured. A hole is formed in the bottom side of the tube 8 near its inner end, said hole registering with a hole laterally extending from the opening II, as shown in Fig. 4. An elbow I8 is secured within said holes and projects along the tube 8 at about the axial center thereof. An extension I 9 is loosely fitted to the end of the elbow and is adapted to receive a flexible tube projecting Within the tube Il at about the axial center thereof.v In fact the tubes I1 and 20 may comprise a single structure if desired. 5 An applicator 2| is secured to the bottom face of the head 9 in any suitable manner, a gasket 22 ybeing interposed between the head and the applicator as shown in Fig. 4. A recess 23 preferably of rectangular shape is formed in the top 10 of the applicator, as shown in Figs. 4, 6, andv 7, said recess registering with the chamber IU, the latter of'which is located substantially in the center of said recess. Another recess 24 is formed in the bottom of the applicator, the side walls of this recess preferably tapering from a. wider dimension at the mouth of the recess to a narrower dimension at the bottom. Holes 25 open from the bottom of this recess into the recess 23 and into the chamber I0.

Ay groove 26 is formed in the top of the applicator, extending around the recess 25 at a distance therefrom, as shown in Fig. 7, and passages 21 extend from said groove downwardly. yTeeth 28 are formed on opposite sides of the recess 24, and the passages 21 open through said teeth near the outer ends thereof, as shown in Figs. 4 and 6. vTufts 29 of bristles are secured within holes Ain an overhanging ledge on opposite sides of the applicato-r in the top thereof, these tufts constituting a brush structure located flush with the outer endsI of the teeth 28.

In use the tube 20 is secured to a source of air supply under some pressure and the tube I1 may be connected with a suction device, and the applicator being applied to the scalp and rubbed thereover, a volume of air through the passages 2 1 will be applied to the hair and scalp. The rubbing'action of the applicator will wrinkle the scalp 'more or less. The teeth 28 aided bythe brush. 29 will loosen any dandruf from the scalp and suctionfthrough the tube I1 will remove such dandru'i. It will be found that the massaging action of the teeth, which in fact comprises a comb, upon the hair and scalp together with the brush will produce beneficial results from a massaging standpoint and the device as a whole is of a most` satisfactory character from the beneficial results gained by its use. Y

My improved implement may be used with various kinds of fluids although air has been speciiically mentioned, and the direction of flow of fluid currents may be varied as desired and it will be obvious that the fluid may be employed for administering medicaments to the scalp if 55 desired. The curved shape of vthe bottom of the recess 24, when suction is employed in said recess, will tend to impart a curling eifect to the hair, and when warm air is employed the hair may be quickly dried. The diagonal arrangement of the outlets of the passages 21 into the recess 24 delivers the air at an angle to the roots of the hair, and this pressure will tend to impart a vibrating movement to the scalp creating wrinkles thereof in `addition toV that obtained by the rubbing action of the teeth of the comb. This delivery of the air currents at an angle to the hairs avoids a direct application to the hair roots which conceivably might result in injury to such roots. The staggered arrangement of such Iteeth enables :practically the Whole surface of the scalp to be covered in the rubbing action, this arrangement in effect providing a double comb. The ends of the recess 24 in effect each -constitutes a broad curved tooth to conform more or less to the surface of the scalp, and the bristles act as a guard to prevent free exit of air from the recess under the edges thereof and thereby cause it to pass upwardly through the holes 25.

The modification shown in Fig. 9 is the same as that shown in the preceding figures with the exception that the teeth 30 on opposite sides of the recess 24 are staggered relatively to each other.

In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out.
